Android startActivityForResult请求代码与启动google voice to text时给出的代码不同

在我的应用程序中，我正试图从一个片段中使用ReconfizerIntent启动谷歌语音到文本。请求代码的值为1010，但在startActivityForResult上，返回的请求代码为197618

请求变量已设置为：

// static result code, random integer
public static final int REQUEST_CODE_VOICE = 1010;

// set intent for recognize speech
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

onActivityCreated方法的片段，其中意图已启动：

public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    // put language
    //intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    //intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en-US");
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
    intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
            getString(R.string.speech_prompt));

    // tap button on click listener
    btnTap.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            try {
                // start activity
                Log.d("onActivityResult", "voice activity started");
                startActivityForResult(intent, REQUEST_CODE_VOICE);
                Log.d("onActivityResult", "voice activity finished");
            } catch(ActivityNotFoundException e) {
                // the device does not support android speech
                showToast("Your Device Does Not Support Speech Recognition!");
            }
        }
    });
}

以下是MainActivity中的onActivityResult方法

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    Log.d("onActivityResult", "request: "+requestCode+", result: "+resultCode);

    switch(requestCode) {
        // Speech to Text
        case VoiceControllerFragment.REQUEST_CODE_VOICE:
            // get the results
            ArrayList<String> text
                    = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
            // show results
            TextView tvRecognizedText = (TextView) findViewById(R.id.tv_recognized_text);
            // tmp string
            //String tmpStr = "";
            tvRecognizedText.setText( "Success: " );

            Log.d("onActivityResult voice", "result: "+RESULT_OK);

            if(resultCode == RESULT_OK && data != null) {
                // concatenate all results
                for(String str : text) {
                    tvRecognizedText.setText( tvRecognizedText.getText().toString() + str );
                }
                Log.d("speech", text.get(0));
            } else {
                tvRecognizedText.setText( "Sorry! Unrecognizable speech.\nTry again!!" );
            }
            break;
    }
}

尝试在onActivityResult（）中使用此选项

res=requestCode&0xffff
然后像往常一样勾选“res”。
试试这个：

。。。
getActivity（）.startActivityForResult（意图、请求、代码、语音）；
…

这是我的工作
 对于那些和我一样明白这一点的人-如果您正在呼叫
startActivityForResult（意图、请求、代码、声音）来自片段-向其添加
getActivity（）
，如下所示：

getActivity（）.startActivityForResult（意图、请求、代码、语音）

如果没有它，您的
onActivityResult（）
方法将使用各种请求代码触发，但需要的请求代码除外（您在
startActivityForResult（）中使用的代码）

希望这能帮助别人
